Seems to me that I should be doing something on the master site prior
to creating anything on the replicating side, however I can't find in
the docs what that something should be.

Can someone please direct me into the right direction?

(btw, the link works, other non-updatable ones refresh fine, with
exception of few that i now know how to fix)
